Caltech's smart bandage clears new hurdle: monitors chronic wounds in human patients
2025-04-23
Caltech professor of medical engineering Wei Gao and his colleagues are envisioning a smart bandage of the future—a "lab on skin" that could not only help patients and caregivers monitor the status of chronic wounds but also deliver treatment and speed up the healing process for those cuts, incisions, scrapes, and burns that are slow to heal on their own.
In 2023, Gao's team cleared the first hurdle toward achieving that goal by showing that a smart bandage they developed could provide real-time ...

“Our discovery has found a possible treatment that could specifically target and help patients with this disease”
(Boston)—The global burden of chronic kidney disease (CKD) is rising, with more than 800 million people affected worldwide. Vascular diseases in patients with CKD are unique and grouped as uremic vascular diseases. One of them, calciphylaxis, typically affects patients with end-stage, advanced kidney disease. It is a condition characterized by severe, painful and non-healing skin ulcers with no known cure.
For the first time, researchers from Boston University Chobanian ...
FRESH bioprinting brings vascularized tissue one step closer
2025-04-23
Collagen is well-known as an important component of our skin, but its impact is much greater, as it is the most abundant protein in the body, providing structure and support to nearly all tissues and organs. Using their novel Freeform Reversible Embedding of Suspended Hydrogels (FRESH) 3D bioprinting technique, which allows for the printing of soft living cells and tissues, Carnegie Mellon’s Feinberg lab has built a first-of-its-kind microphysiologic system, or tissue model, entirely out of collagen. This advancement expands the capabilities of how researchers can study disease and build tissues for therapy, ...
Chinese scientists prove swamp forest collapse linked to human activity
2025-04-23
Chinese scientists have discovered that fragile swamp forests in the Pearl River Delta (PRD) region suddenly collapsed around 2.1 thousand years ago (ka)—with human activity as the cause.
The study, led by researchers from the Guangzhou Institute of Geochemistry and the Institute of Oceanology of the Chinese Academy of Sciences, sheds new light on the role of human activity in ecosystem collapse.
Published in Science Advances, the study focuses on Glyptostrobus pensilis (G. pensilis), a critically endangered species of Chinese swamp cypress that once thrived in extensive swamp forests in the PRD. Through palynological (i.e., pollen and ...

University of Houston engineer reinvents ceramics with origami-inspired 3D printing
2025-04-23
In a breakthrough that blends ancient design with modern materials science, researchers at the University of Houston have developed a new class of ceramic structures that can bend under pressure — without breaking.
Potential applications for this technology range from medical prosthetics to impact-resistant components in aerospace and robotics, where lightweight - but tough - materials are in high demand.
Traditionally known for their brittleness, ceramics often shatter under stress, making them difficult to use in high-impact or adaptive applications. But that may soon change as a team ...
How an antimalarial drug could help fix genetic diseases
2025-04-23
The antimalarial drug mefloquine could help treat genetic diseases such as cystic fibrosis, Duchenne muscular dystrophy, as well as some cancers.
In these diseases, a mutation in the genetic code introduces a stop signal in completely the wrong place, leading to the production of a shortened protein. An international team of researchers, including scientists of the University of Groningen, have now demonstrated how the antimalarial drug mefloquine can enhance the effect of aminoglycosides, another class of drugs, to override ...
Severe, lasting impairment that some consider ‘worse than death’ affects many residents after long-term care admission
2025-04-23
Ottawa, ON, April 23, 2025 – 20% of residents newly admitted to long-term care became permanently unable to make everyday decisions for themselves within five years, according to new research from Bruyère Health Research Institute and ICES.
A significant number of long-term care (LTC) residents experience states of severe cognitive and physical impairment, leaving them unable to make personal decisions—like what to eat or what to wear—and unable to communicate with staff or loved ones.
“Our study set out to trace the experiences of residents newly admitted to long-term care, and ...
Cognitive and functional decline among long-term care residents
2025-04-23
About The Study: In this study, severe permanent impairment in function and cognition were common and often present near the end of life for long-term care residents, but a minority of residents lived in these states for years. These results suggest that building shared understanding and open communication about the natural course of frailty trajectories for long-term care residents may support resident-centered medical decision-making.

Screening and response for adverse social determinants of health in US emergency departments
2025-04-23
About The Study: Despite the high prevalence of adverse social determinants of health (SDOH) in emergency department (ED) populations, in this survey study of 232 EDs, less than one-third performed screening, and one-fifth did not have policies requiring a response to positive screens. Bridging this gap may require expanding adverse SDOH screening practices while also ensuring that EDs have the resources and infrastructure to respond appropriately to identified social needs. Future research might explore advanced technological solutions ...
How DNA self-organizes in the early embryo
2025-04-23
Early DNA Organization is Robust and Flexible
When the egg and sperm fuse, a comprehensive reorganization of DNA begins within the nucleus. Epigenetics plays a crucial role in this process, regulating gene activity through chemical modifications on DNA and its associated proteins. “We wanted to understand how these epigenetic programs influence gene activity and ensure that the cell correctly executes its developmental tasks,” explains study leader Prof. Maria-Elena Torres-Padilla, Director at the Institute of Epigenetics ...
Remembering the cold: scientists discover how memories control metabolism
2025-04-23
New multidisciplinary research led by Prof. Tomás Ryan from Trinity College Dublin shows that the brain forms memories of cold experiences and uses them to control our metabolism. This newly published study is the first to show that cold memories form in the brain – and map out how they subsequently drive thermoregulation.
The discovery may have important applications in therapies designed to treat a range of disorders – from obesity to cancer – in which thermoregulation and metabolism (or a lack of control in this area) plays a role, as ...
Phoenician culture spread mainly through cultural exchange
2025-04-23
To the point
Secret of the Phoenician-Punic civilization's success: Their culture spread across the Mediterranean not through large-scale mass migration, but through a dynamic process of cultural transmission and assimilation.
Melting pot of ancient people: The study found that Punic populations had a highly variable and heterogeneous genetic profile, with significant North African and Sicilian-Aegean ancestry.
Highly interconnected: Ancient Mediterranean societies were cosmopolitan, with people from different regions trading, moving often over large distances and having offspring with each other. This provides new insights into the region's cultural and population history in ...
Smoking cessation drug varenicline helps young adults quit vaping
2025-04-23
A new study by investigators from Mass General Brigham showed that teens and young adults who took varenicline—an FDA-approved, twice-daily smoking cessation pill for adults—are more than three times as likely to successfully quit vaping compared to those who received only behavioral counseling. Results are published in JAMA.
“Vaping is extremely popular among kids, and we know that this early nicotine exposure can make drugs like cocaine more addictive down the line, yet ours is the first ...
How bacteria in our aging guts can elevate risk of leukemia and perhaps more
2025-04-23
CINCINNATI—Scientists at Cincinnati Children’s along with an international team of researchers have discovered a surprising new connection between gut health and blood cancer risk—one that could transform how we think about aging, inflammation, and the early stages of leukemia.
As we grow older—or in some cases, when gut health is compromised by disease—changes in the intestinal lining allow certain bacteria to leak their byproducts into the bloodstream. One such molecule, produced by specific bacteria, acts as a signal that accelerates the expansion of dormant, pre-leukemic blood cells, a critical step ...

2025-04-23
The total economic burden of Alzheimer’s disease and related dementias in the United States will reach $781 billion this year, according to new USC-led research.
This is the first of what will be annual national estimates from the multidisciplinary research team. The team aims to provide the most comprehensive accounting yet of dementia’s growing economic toll. Beyond the cost of care, the model also accounts for lost earnings from patients and care partners who cut back work hours or leave jobs, ...
Childhood exposure to bacterial toxin may be triggering colorectal cancer epidemic among the young
2025-04-23
In an effort to explain a modern medical mystery, an international team of researchers led by the University of California San Diego has identified a potential microbial culprit behind the alarming rise in early-onset colorectal cancer: a bacterial toxin called colibactin.
Produced by certain strains of Escherichia coli that reside in the colon and rectum, colibactin is a toxin capable of altering DNA. Now, scientists report that exposure to colibactin in early childhood imprints a distinct genetic signature on the DNA of colon cells—one that may ...
Epigenetic aging detected in baboons, but physical decline not clearly linked
2025-04-23
“[…] these data demonstrate that baboons exhibit varying degrees of differences between their chronological and epigenetic ages (i.e., their delta age), allowing characterization of baboons as age-accelerated or decelerated.”
BUFFALO, NY — April 23, 2025 — A new research paper was published in Aging (Aging-US) Volume 17, Issue 3, on March 18, 2025, titled “Epigenetic and accelerated age in captive olive baboons (Papio anubis), and relationships with walking speed and fine motor performance.”

Latest ACS cancer prevention and early detection report: Smoking rates continue historic drop, but cervical cancer prevention is lagging
2025-04-23
In a new report released today, American Cancer Society (ACS) researchers discovered mixed progress in major cancer risk factors, preventive behaviors, and screenings in the post-COVID-19 pandemic period among adults in the United States. Smoking rates continued a long-term declining trend during the COVID-19 pandemic, but 27 million adults still smoked in 2023. Breast and colorectal cancer (CRC) screening rebounded after decreasing or stalling during the pandemic. However, past-year cervical cancer screening remained lower than pre-pandemic levels, continuing a disappointing pattern in up-to-date screening in the past two decades. ...
Toxic blooms in motion: Researchers map algae patterns in Lake Okeechobee
2025-04-23
Lake Okeechobee, Florida’s largest freshwater lake, plays a vital role in the state’s ecosystem and water management. Spanning 730 square miles with an average depth of just 9 feet, it serves as a crucial water source for agriculture and flood control. Connected to the Everglades through canals, it’s also a popular destination for fishing, boating and birdwatching.
However, the lake faces increasing harmful cyanobacteria blooms, particularly from the toxin-producing species Microcystis aeruginosa. These microscopic algae thrive in warm, nutrient-rich waters and can form harmful algal blooms. Known for their diel (daily) vertical migration, cyanobacteria move up ...
